Linux Open-Source Virtualization Roadmap
Abstract : Linux supports multiple open-source technologies for
virtualization, the most popular being Xen, KVM, OpenVZ and Vservers. Each
has its strengths, weaknesses and tradeoffs, so selecting the right one
for your environment is non-trivial.
This talk will cover the capabilities of the four major virtualization
types, in the following areas.
Resource use : All methods of virtualization impose an overhead in
addition to the cost of processes running within each virtual machine.
However, this overhead varies between KVM (the most expensive) and OpenVZ
(the cheapest).
Isolation : Virtual machines should be ideally isolated from each other
and from the host system, and be limited in the amount of CPU, RAM, disk
space and network bandwidth they can use. However, in practice the level
of isolation depends on the technology used - Xen performs with best,
Vservers the worst.
Manageability : A good virtualization technology makes it easy to create,
manage, move and destroy virtual systems. Each of the four types has its
own tools, commands and configuration file format.
Flexibility : Some virtualization methods like OpenVZ and Vservers can
only run Linux, while others like Xen and KVM can run almost any operating
system, if they have the required hardware support.
Future support : Each technology is developed by different groups, and not
all are as well maintained. KVM is the leader here, as it is now part of
the Linux kernel, while Vservers seems to be falling behind.
Jamie Cameron, Webmin
Jamie is the developer of Webmin, a popular open-source web-based system
administration took for Linux and Unix systems. He also works on
Virtualmin (a web hosting control panel) and Cloudmin (an interface for
managing virtual systems).
RSVP
Although it is not required, we like to have an idea of how many
people to expect, so if possible please email rsvp@penlug.org if you
are planning to attend.
GETTING THERE
For information on getting to the meeting, please see:

Traffic on 101 can be pretty bad in the evening, so we encourage you
to check traffic conditions before driving by dialing 5-1-1 on your
phone or visiting www.511.org, and if possible to take public transit
(best bet: bicycle via Caltrain) or carpool to this meeting.
